1 Claim. l

The holder of my invention is especially adapted for the holding ofelongated cylinders such as fire extinguisher cylinders, securely inpartly exposed position, under tension, and, at the same time, to permitof the instantaneous removal of the cylinders therefrom when desired.

An embodiment of a structure employing my invention is shown in theaccompanying drawings and described in detail in the ensuingspecication. This embodiment is merely by way of eX- ample; my inventionis not limited thereto but includes all other forms which would comewithin the scope of the appended claims. in the draw ings,

Fig. 1 is a vertical sectional view of a cylinder holder embodying myinvention,

Fig. 2 is an elevational View thereof; taken on line 2 2 of Fig. l, and

Fig. 3 is a View similar to Fig. l, showing `a fire extinguishercylinder positioned in the holder of my invention.

As shown in the drawings, the holder of my invention comprises a memberit of generally U-shaped cross-section, open at the upper end l Ithereof and closed at the lower end, i2 thereof, said lower end l2 beingrounded and being provided with a medial boss I3 on which the nozzle endof the cylinder 22 is supported and is thus sealed from the atmosphere.The holder It is provided with lugs ill and l5 at the upper and lowerends thereof, said lugs having apertures it and I6 for the reception ofscrews or like holding means S to fasten the holder to a wall or othersupport W. The cylinder is provided with spring means to maintain thecylinder under tension therein and centered on the boss i3. As shown inFig. 1, said spring means comprises a spring member l l xed at one endto the holder by means of a rivet i8 or the like, the spring beingpreierably bowed, as at le to normally project into the holder. Thelower end of the holder is provided with a medial rib 20 which isconnected with the rear wall 24 of the holder and with the depending lugI5, and which thus serves to renforce the lower end of the holder.

The holder may be made of metal or plastic or of a combination of suchmaterials or of any other desired or convenient material, the partsbeing so proportioned that the internal diameter D of the holder will beslightly larger than the external diameter of the cylinder 22 to be heldtherein.

As will be noted from Fig. 3, the cylinder 22 upon being positionedwithin the holder, ilattens the bowed portion i9 of spring il, therebymaintaining the cylinder tightly within the holder. The nozzle end 23 ofthe cylinder 22 rests on the medial boss I3 at the lower end of theholder so that the nozzle end of the cylinder is substantially sealedfrom the atmosphere, precluding the possibility of contamination of thenozzle end oi the cylinder and of the discharge aperture thereof.

It will be apparent from Fig. 3 that on inserting the cylinder 22 intothe holder, the cylinder automatically aligns itself onto the medialboss i3 and is held tightly or under tension in the holder with theexposed end of the cylinder projecting above the open end H of theholder in position for rapid and effortless removal of the cylinder whenso desired.

While I have described the holder Ei) as used for the reception of thei'lre extinguisher cylinder 22. it will be apparent from the foregoingdescription that the same may be used for the holding of other objectsof similar kind in the same fashion.

I have shown in the drawings and described in the above specication, aconvenient form oi 25 structure embodying my invention; it will beapparent from such disclosure that the invention is capable of manymodifications without departing from the spirit and scope thereof, assetforth in the appended claim.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is:

A holder for a cylinder having a nozzle, said holder comprising a memberci generally U- shaped cross-sectional outline having a rounded, closedlower end and an open upper end, a medial boss in the lower end of saidholder on whichv the nozzle of the cylinder may rest, and spring meanssecured to the holder and projecting thereinto to hold the cylinderpositioned therein tightly on the boss.
